Errors-To:
linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org
With the current range specified for the CPU interface there is an
error message at boot:
GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
Setting irqchip.gicv2_force_probe=1 in bootargs results in:
GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB
GIC: Adjusting CPU interface base to 0x000000001032f000
GIC: Using split EOI/Deactivate mode
Using the adjusted CPU interface base and 8K size results in only the
final line remaining and fully working system as well as /proc/interrupts
showing additional IPI3,4,5,6:
IPI3: 0 0 CPU stop (for crash dump) interrupts
IPI4: 0 0 Timer broadcast interrupts
IPI5: 0 0 IRQ work interrupts
IPI6: 0 0 CPU wake-up interrupts
